Even though the IBM Knowledge Center contains the technical product documentation for thousands of IBM products, you can easily and quickly get information about only the products and topics that you are interested in.
For a great summary of how to select your products to refine your search filters, check out the January 31 entry by Jamie Roberts in the IBM Technical Content blog (https://ibm.biz/BdRfCC).
To reduce the number of results returned about a particular subject area, you can refine your search by using the intitle operator. The intitle operator restricts results to words or phrases that appear only in the title of a topic. Use this operator when you are looking for the main topics about a subject area. For example, compare the following two searches for Informix 12.1:
1. basic text search error
This simple search returns 84 topics. The 4 terms might appear anywhere in a topic or in the topic title.
2. basic text search intitle:error
This search returns 3 results. It returns only topics with the word error in the title, and with all of the following words anywhere in the topic: basic text search
You can also search for a phrase in the title. For example:
This search returns 4 topics. All the topics contain the phrase sqlhosts registry in the title.
